To all 'whom t may concern:

Be it known that I, CARL F. ANDERSON, a citizen ofthe United States, residing at Chicago, `in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding and Wrapping Machines, of which the following is a speciiication. x

This invention relates to machines .for folding magazines, newspapers, or the like, placing a wrapper about each magazine or paper, and pasting together the ends of the wrapper. In prior machines of this character, when for any reason a wrapper was not placed in position to be folded about the magazine, the paste was deposited directly on the magazine. By reason of this failure of the operator or machine to supply the wrapper, the corresponding magazine was spoiled through the mis-application ofthe paste, and the properly wrapped magazines among which the unwi'apped magazine was deposited were smeared with paste, as was also that portion of the mechanism thatI came into contact with the unwrapped magazine.

One of the objects of this invention is to remedy the evil above referred to.

Another object is to provide improved means for applying the paste.

A further object is to improve the Wrapper-folding means.

Another object is to provide means governed by the magazine for controlling the feed'of the wrappers.

In the accompanying drawings, Figure l is a longitudinal section through a machine embodying the features of my invention.v

Fig. 2' is a fragmental sectional view taken in a plane at right angles to the plane of Fig. l. Fig. 3 is a fragmental top plan view of the detector mechanism. Fig. 4 is a fragmental elevation of the side opposite to that shown in Fig. l. Fig. 5 is a perspective view of a Wrapped magazine. Fig. 6 is a detail view showing the means for controlling the feed of vthe wrappers.

The framework of the machine may be of any suitable construction. Herein it is shown as comprising the end frame members l and 2 rigidly secured together. In this framework are supported tapes for feeding a wrapper ato a predetermined point in the machine; rollers and tapes for folding a magazine b and depositing the folded magazine on the wrapper; other rollers for folding the Wrapper about the folded magazine; lmeans for applying paste to a portion of the wrapper before the wrapperfolding operation is completed; and means for conveying the wrapped magazine to a suitable receptacle.

/' The ,wrapper conveying means may be of any ordinary construction. Herein it is shown as consisting of three endless continuf ously driven tapes 3 extending transversely through the machine and running at one end over a roller 3EL and at its outer end over a stationary feed roller 3b, the latter roller being mounted in a bracket upon the frame member 2. A feed table 4 is arranged adjacent to the feed roller 3b. The upper run of thetapes 3 is supported upon a horizontal stationary table 75. Above the tapes is lol cated suitable guide means 6 which may be of the ordinary or any preferred character.

7 is a stop for limiting the movement of the wrapper. s y

To control the feed of the wrappers, I provide the following described means.` An arm 3c (Fig. 2) is fixed upon a rock shaft 3d which is mounted in suitable bearings'inv the machine frame. The arm 3 carries at its lower end a roller adapted to contact a rotary cam 39. A pair of arms 3f also iiXed on the shaft 3d (only one of the arms being shown in the drawings) carry at their Outer ends a feed roller 3g. The operator moves the sheets of paper along the table 4 onto the feed roller 3" and the forward end of the conveyer 3, and the cam 3e in its rotation causes the periodic descent of the feed roller 3g into contact with the paper lying on the stationary roller 3b to cause the sheet of.

paper to be fully moved onto the conveyer 3 which. thereafter carries it into the ma'- chine. I have provided means for controlling the swinging movement of the arm `3c consisting, in this instance, of endless con-k tinuously-d riven tapes, only one tape being showny in the drawing. f

l0 is guide means located above the conveyer 9, and 11 are guides into the space between which the magazine is moved by the conveyor.

12 isa stop for arresting the travel of the magazine. When so arrested, the magazine lies above a pair of folding rollers 13 and 14, the central portion of the magazine being, in this instance, directly above said rollers. A folding blade 15 carried by arms 16 mounted upon a shaft 17 (all of which may be of the ordinary construction) pushes the middle ortion of the magazine downwardly until 1t is caught by the folding rollers 13 and 14, whereupon said rollers draw the magazine downwardly between them, thereby folding the magazine. As shown in Fig. 1, the conveyer tapes 9 run between therollers 13 and 14 and thence about a folding roller 18. After the magazine has passed between the folding rollers 13 and 14, the conveyer carries the folded magazine to the folding roller- 18 and its coperating roller 19, the folded edge of the magazine impinging against a stop 20.

21 are guides to prevent displacement of the magazine.

Directly below the pair of folding rollers 18 and -19 is a pair of presser rollers 22. The rollers 18 and 19 are spaced a slight distance apart in' order to facilitate the entrance of the folded magazine into the space between said rollers.

23 is a folding blade similar to the blade 15. These blades are swung in unison by means of a ca'm 23a (Fig. 4) fixed on the shaft 23b and acting upon a roller carried 4by an arm 23d which is fixed on the shaft 17.

The arms that support the folding blades 15 and 23 are connected for synchronous move ment through the medium of cra'nk arms 23e and a link 23 A compression spring 23g holds the roller on the arm 23d against the cam 23a. The folding blade 23 bends the magazine downward sufficiently to enable the rollers 18 and 19 to engage it, whereupon said rollers draw the magazine downwardly through the space between them, thereby ims parting the second and final fold to the magazine. Upon passing through the space between the rollers 18 and 1 9, the magazine passes between the pressing rollers 22, whereov tne magazine is subjected to consideraole pressure in order to Hatten the folds.'

The table 5 and the stop 7 are so arranged that the positioned wrapper is below and adjacent to the pressing rollers 22. In this instance, the- Wrapper is intended to be wrapped about the magazine and the ends of the wrapper pasted and lapped. Two

folds are therefore given to the wrapper, the folded wrapper being formed of three portions, d and e, (Fig. 5) of approximately equal width.

In the table 5 is a slot 24 of sufiicient size to allow a magazine and wrapper to pass downwardly therethrough. Said slot is directly below the adj acont portions of the peripheries of the presser rollers 22. As the folded magazine is fed downwardly by the presser rollers 22, the magazine strikes the wrapper lying upon the table 5 and pushesv said wrapper before it as it continues moving downwardly. The magazine and wrapper, as they pass through the slot 24, are caught by rollers 25 and 26, the downward movement of the magazine being 'arrested by means herein shown as comprising three arms 27 having stop lugs 28 thereon. These arms are fixed upon a shaft 29 which is rigidly mounten 1n the free ends of two arms 30. '1`hc arms 30 are fixed upon a rock shaft 31 journaled in the frame members 1 and 2. Guides 25u similar to the guides 11 and 21 serve to prevent displacement of the magazine and wrapper.

32 is a folding blade of any suitable character arranged to press the wrapper and the adjacent edge of the folded magazine far enough toward the roller 26 and a coperating folding roller 33 to enable said rollers to engage the wrapper and magazine and complete the folding of the wrapper. Said blade is carried by arms 321l fixed on a shaft 32h, said shaft having an arm 32 bearing a roller which is acted upon by a cam 32d fixed arms 30 as described, and have provided a.

constantly rotating cam 35 underlying a roller 36 carried by one of the arms 30. A compression spring 36a holds the roller 36 against the cam 35. As the cam revolves, the arms 30 will be alternately raised and lowered. The cam 35 is fixed upon the shaft 34.

In order further to assist in starting the magazine and wrapper between the rollers 26 and 33,1 provide means for separating said rollers slightly. The roller 33 is journaled in arms 37 and 38 fixed upon a rock shaft 39 supported in the frame members 1 and 2. This shaft is turned to lower the roller 33 by means of a cam 40 fixed on the r'constantly driven shaft 23h, said cam acting herein shown comprises' a fountaini 43 in which two rollers 44 and 45 revolve. A plate 46 having a suitable number of lingers 47 thereon is attached to an arm 48 which is fixed upon a rock shaft 49. The shaft 49 is arranged to be oscillated by means of a cam 50 acting upon a roller 51 carried by an arm 52 which is rigid with the shaft 49. A compression spring 51a holds the roller 51 in contact with the cam 50. Said cam is of such form as to cause the fingers 47 to be advanced into contact with the periphery of the paste-carrying roller, then withdrawn out of the way of the descending magazine, and then advancedto place their coated end in contact with the portion 0 of the wrapper. In Fig. 5, f indicates the dabs of pastel deposited on the wrapper by the fingers 47. In the succeeding operation of imparting the nal fold to the wrapper, the portion e of the wrapper is pressed against the pasted side of the portion c of the wrapper, whereby said wrapper portions are caused to adhere to each other. The wrapped magazine, vwhen it emerges from between the rollers 26 and 33, is received between two conveyers 53 and 53a and vis deposited in a receiving trough or packer box 54 of ordinary construction; The upper conveyer 53a is run ata lower speed than the lower one, so that it exerts a rubbing action upon the overlapping fiap of the -wrapper to cause the wrapper to be drawn snugly about the magazine.

I have provided means for preventing the application of paste to a magazine for which no wrapper has been supplied. This result vis accomplished in the present instance by rendering inoperative the paste-applying dee vice whenever a magazine 1s presented about which no wrapper has been placed. The arm 52 which moves the arm 48 and pasteapplying fingers 47 is extended beyond the roller 51 and has an angular projection 52a upon its free end. A vertical lever 55 is pivoted between its ends at 55a in the frame work. A coiled compression spring 56 surrounding a rod 57 which is attached to the upper portion of said lever tends to swing the lever to carry its lower end in position to obstruct the upward movement of the projection 52a on the arm 52, and thus hold the paste-applying fingers 47 in inoperative position. A roller 58 carried upon the upper portion of the lever 55 is engaged by a cam 59 fixed upon the shaft 23T so that the leverv 55 is given an oscillatory movement.

Means is provided for normally holding the lever 55 out of the path of the projection 52a yon the arm 52, and for preventing the roller 58 from following the contour of the cam- 59. This means comprises a detector 64' pivoted at 65 to a bracket 66 fixed to a stationary supporting rod 67. The lower por' tion of said detector is curved and lies in position to be lifted by a wrapper which is being" positioned upon the table 5. ,Said'detector has an upwardly-extending linger 68 which normally underlies one arm 69 of af vertically disposed bell crank' also mounted upon the bracket 66. The other army 70 of ','o said Vbell crank is connected by a link 71 to one arm of a horizontal bell crank 72 mounted on a bracket 73 fixed in the framework.

The other arm of the last mentioned bell crank is connected through the medium of a ',5 link 74 to the upper, end of the lever 55. When a wrapper underlies the detector 64,

the end of the finger 68 lies beneath the arm 69 and prevents the spring 56 from rocking the lever 55 far enough to engage thel lug 52a 8o on the lever 52. If no wrapper is supplied at the proper time, the detector 64 swings downwardly from beneath the bell crank arm 69, thereby allowingthe spring 56 to rock the lever 55 and place its lower end in the S5 path of the lug 52a so that the paste-apply ing fingers will not contact the magazine for which no wrapper has been provided. It will be understood from Fig. 2 that the detector 64 normally lies upon a wrapper, and that the wrapper lies upon the tapes 3, the latter in turn being supported upon the table 5. When no wrapper is present, the detector swings downwardly through the space between the tapes and into contact with the table 5, such` .downward movement being sufficient to withdraw the upper end of the finger 68 from below the bell crank arm 69 and prevent operation of the pasting mechanism. f ico In order to control the feed of the wrappers in accordance with the magazines siipplied to the machine, I provide a horizontal rock shaft 77 upon one end of which is fixed a finger 78 having a weighted end 7 9. The weight of this finger normally tends to raise one end thereof between the tapes 9, and into the path of the magazine just after it passes between the folding rollers 13 and 14.V On the lother ,end of the rock shaft 77 is fixed a dependingy arm 80 having a'notched end adaptedto engage a laterally projecting lug 81 on the arm 3c which controls the wrapper-feeding roller 3g (see Figs. 2 and 6). When the arm 80 is in engagement with the -lug 8 1, the roller on the lower end of the Aarm 3c does not follow the contour of the cam 3e, and the movable feed roller 3g remains stationary in its lifted position.v IlVhenever a magazine contacts the upwardly extending end of the finger 78 the 'finger is depressed, the rock shaft 77 is rotated, and thearm 8O is withdrawn from the lug 81 to permit the feed rollers 3g to descend and move a wrapper onto the conveyer 3. Thus 12,5 it will be seen that when no magazines are being fed to the machine, no wrappers will be supplied to the conveyer 3.

vA bracket 84 is mounted at one end upon a cross bar 85 on the framework, and this 130 T40.. feeler finger occupies the obstructing posiscription'. 'driving the various shafts has been omitted bracket carries at its other end a register or I counting device 86. This register is operated by an arm 87 thereon which overlies and bears against the upper edgeof the first folding knife 15. A spring comprised in theregister normally presses the operating arm downwardly and said arm is moved upwardly to actuate the register by the folding knife 15,. A feeler finger 88 is pivoted between its ends to a downwardly projecting lug on the'bracket 84, the lower end of said feeler finger being arranged to lie in the path of a magazine presented by the conveyer 9. The upper end of the feeler finger is notched or shouldered to engage a projecting pin 89 on the register-actuating arm 8,7. So long as magazines are continuously fed to the machine, so that a magazine will always underlie the lower end of the feeler finger, the upper end thereof will be held in inoperative position` as indicated in'Fig. 1.

The actuating arm 87 will therefore follow the movements of the folding knife 15.' When, however, no magazine is present beneath the feeler finger 88, the lower end of said finger will swing downwardly, and thus carry the upper notched end into engagement with the pin 89 and prevent the actua-.. rtion of the register until another magazine is presented. With the parts 'in this position, each time the folding knife rises it engages 'the actuating arm 87 and raises it slightly out of contact with the feeler nger,

.so that should a magazine be presented by the conveyer 9, the finger can be easily swung by the magazine, since the friction between the finger and the stop pin 89 has y been removed by the raising of the actuating arm.v Until a magazine is presented, the

tion, the actuating arm 87 being raised slightly each ltime the folding knife 15` reaches the upper end of its movement. As

. will be seen, when magazines are being regularly fed, each time the folding knife descends a magazine will be folded and the register will be actuated, so that an accurate account ofthe magazines passing through the machine will be recorded. `llvhether or not there is a magazine present beneath the folding knife, saidl knife descends'regularly, but in' this case the feeler finger prevents the actuation 'of the register.

The operation of the machine will, it is thought, be clear from the foregoing de- Illustration of the means for from the drawings, as the invention does not relate thereto and any common or suitable driving means m-ay be employed.

For the sake of brevity, the term magazine is used inthe claims to denote magazines, catalogues, newspapers and analogous magazines, and means arranged to prevent the application of paste directly to a maga.- zine in case it should be presented without a wrapper thereon.
